Be it known that lvl/Timmer D. EN ris, a citizen of the United States,residing` at Richtorc, in the county et liranllzlin and State etTilerinont, has invented certain new and useful ln prevernents in lleodSteamers7 of which the followin is a specitlcatior. m1; f. .my i n. .42a ,1 i e n1 l Lis invention as lcieicnce Le ooo.v Steamers ier t; ofwood prepara- 'tory to presenting' the logs to knives to cut them intoveneer strips, and its object is to so sollten thewoou to prepare it forcutting` into long strips or" veneer when the steamed Wood is mounted inan appropriate lathe.

ln accordance with the invent n, the lo oi Wood are lowered into a vat-with one end ot the vat slightly higher than the other and the logs areconveyed tiret downwardly into the vat of Water and then upv:ardlg,Ttherefrom, the Wood being; snbiected to streains of steam which heat am.saturate the wood as it is being` treated.

ln order that this opration nia-y be aeconiphshed, tue logs are feo bychains l v q .il tl n .03 n 4- Vyn; y. (LOW lllvhll( .Ly HL @M2311 le(lo 0... u e0/L through which the jets of steam are conducted and thenupwardly frein the vat at the upper end thereof. The length of the lil)vat is suihcient to subject the logs ot weed to the heatingaction or thesteani7 thus permitting the logs to he appropriately sottened. fitterthe steaming action has continued for a suillcient length ottime thelogs are then mounted in suitable lathe and are presented to appropriatecutters tor cutting the logs into strips to produce veneer.

rlhe invention `will be best understood from a consideration et thefollowing detailed description taken in connection with the accompanyingdrawings forming' part of this specification.

ln the drawings:

Figure l is a side elevation et a steaming vat constructed in accordancewith the present invention.

Figure 2 is a section on the line 2 2 ot Figure 1;.

Figure 3 is a central longitudinal section through the steaming; vat.

Figure 4 is a transverse sectional View of the vat on an enlarged scaleand cut on the line L-l of Figure l.

Referring` to the drawings, it will be seen that the reference characterl desig- 1923. Serial No. 49,27?.

an elongated vat i which may be 1 r of concr 1e, the saine being'elongated `with its opi ends 2 and rising)` aso' the nerinal water levelin the vat. rlll/ie y be composed of a trough which has en top closed bya cov-er or hood resti `e top et the side Walls. The hoe mediate portionlyin@` in spa A llelisin with the corresponding por ie or the bott n etthe trough and has its inc-ined end portions disposed in parall'l" thecorresponding' end portions c associated with the bott-oni e' is a ofendless chains 9 which areV trained over the appropriate ovided lt is tobe observed that pulleys provided for this purpose. At longitud nali);spaced points7 the inner stretches et the pairs oit chains are connectedtogether by relatively short and vertically disposed cross chains 10.The vlogs 6 are hunched and confined between the chains i0 in the mannershown.

tween anu on opposite sides oil the rails are the bui ches of logs areadapted Arranged bener-ined steam conveying pipes 5. lt is be noted thatthe pipes are eic the dieneter te lie in a plane below the glane of theupper faces et the rails l5.

'lhe inner run of the chains 7 and 9 more along the interior et' thevat, from the log.;l receiving` end te the leg delivery end thereof. prllhe logs are placed crossvfise upon the inner runs ot the chains l and9 and the lower logs inove upon the upper surfaces ot the rail 15. Thelogs are assembled in groups, and the groups are separated from eachother by Vcross chains l0 which are connected with the inner runs of thechains and 9. W hen the logs arrive at the deliver7 end ol the vat, theross chain sections are disconnected frein the chains '7 and 9 whichpermits trie logs of the groups to roll out of the discharge end of thevat.

That is claimed is:

A piani'J for steaming logs comprising a Vu having a horizontalintermediate poia` tion, and inclined end portions which form thebottoni of the vat, Chains trained 1ongitudinally around the bottoniL ofthe mi;7 rails extending the full length of the bottoni of the vat andmounted heieon, perforated pipe seetions disposed between the rails andlying below the plane in which the lippe:- suifoees of the .rails lie,a. hood spaced from the Vat, said hood having on intelinediaie portionwhich lies paraliel with the intermediate portion of the bottom of thevate, lind inclined end portions which are disposed parallel with thecorresponding end portions of Jche bottoni of the vot, chains trainedaround the hood, cross chains connecting the chains around the hood withthe chains around the Vat, und closures for bridging the :spaceibetweenthe ends o' the hood and the corresponding ends of the vai'. Intestimony whereof I affix my signo'- ture.
